DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

In the following detailed description of illustrative embodiments,reference is made to the accompanying figures of the drawings which forma part hereof, and in which are shown, by way of illustration, specificembodiments which may be practiced. It is to be understood that otherembodiments may be utilized and structural changes may be made withoutdeparting from (e.g., still falling within) the scope of the disclosurepresented hereby.

Exemplary apparatus, systems, and methods shall be described withreference to FIGS. 1-8. It will be apparent to one skilled in the artthat elements from one embodiment may be used in combination withelements of the other embodiments, and that the possible embodiments ofsuch apparatus, systems, and methods using combinations of features setforth herein is not limited to the specific embodiments shown in thefigures and/or described herein. Further, it will be recognized that theembodiments described herein may include many elements that are notnecessarily shown to scale. Still further, it will be recognized thatthe size and shape of various elements herein may be modified but stillfall within the scope of the present disclosure, although certain one ormore shapes and/or sizes, or types of elements, may be advantageous overothers.

Exemplary implements, implement systems, and methods described hereinmay be configured to engage a ground surface and form a pluralityreservoirs in the ground surface. The exemplary implements may includeroller apparatus, and the roller apparatus may include a plurality ofground displacing elements shaped, sized, and/or configured in manydifferent ways which will be described herein with respect to FIGS. 1-8.

As used herein, a “reservoir” may be defined as an indentation, recess,and/or cavity formed within a ground surface configured such that watermay be collected and/or held therein.

An exemplary implement 10 depicted in FIGS. 1A-1C may include a mountportion 20, an extension member 30, and a roller apparatus 40. The mountportion 20 may be configured to be coupled to a vehicle (not shown),such as a tractor, to couple the exemplary implement 10 to the vehicle.The vehicle may be used to pull the implement between rows of vegetationor crops to form a plurality of reservoirs between the rows using theimplement 10. To provide the coupling between the implement 10 and avehicle, the mount portion 20 may include one or more mounting brackets22 configured to be coupled, or attached, to a portion of a vehicle. Asshown, the mounting brackets 22 may define a plurality of apertures, oropenings, 24 through which fasteners, such as bolts, may extend tocouple the brackets 22 to the vehicle.

The mount portion 20 may not be directly coupled to a vehicle, andinstead, may be coupled to apparatus that is coupled to the vehicle. Forexample, the mount portion 20 may be coupled to frame apparatus, suchas, e.g., a beam, or other support member, which may be coupled to thevehicle, such as described herein with respect to FIG. 8. In one or moreembodiments, exemplary frame apparatus may be raised or lowered by thevehicle so as to raise or lower the implement 10 to engage a groundsurface. For example, the mount portion 20 may be couplable to and/orcoupled to a frame apparatus that extends transverse to the forwardmoving direction of a vehicle and the frame apparatus may be coupled toa hydraulic system of the vehicle to raise and lower the implement 10when used in conjunction with the vehicle.

The mount portion 20 may be configured to transmit force to the rollerapparatus 40 from the vehicle to maintain engagement between the rollerapparatus 40 and a ground surface 12 when the roller apparatus 40 isrolled over the ground surface 12 as shown in FIG. 1C. For example, thevehicle may provide a force, or may allow the mass of the implement 10itself to provide a force, to direct the roller apparatus 40 inengagement with the ground surface 12 when in use, and the mount portion20 may facilitate, or transmit, that force to the roller apparatus 40.Additionally, the mount portion 20 may be configured to transmit forceto the roller apparatus 40 by being biased in a clockwise directionabout a pivot axis 14 as shown by arrow 15 when viewing the implement 10from the side as shown in FIG. 1C. Other methods of transmitting forceto the roller apparatus 40 may be used such as, e.g., airbags, a bellowssuspension system, a torsional spring system, a linear spring actuatorsystem, or a rotary or linear hydraulic actuator/accumulator system,etc.

The extension member 30 may extend from a proximal end portion 32 to adistal end portion 34 and may be pivotally coupled to the mount portionabout the pivot axis 14. As used herein, “pivotally coupled” may bedefined as a coupling between objects such that the objects areconfigured for pivotal movement in relation to each other. As depicted,the mount portion 20 may be pivotally coupled to the proximal endportion 32 of the extension member 30 through the use of an elongatetorsion assembly 80 (see, e.g., a “Henschen” suspension as described inU.S. Pat. No. 3,436,069 entitled “Bearing Assembly for Elastic Joints”and issued to Henschen on Apr. 1, 1969 and U.S. Pat. App. Pub. No.2007/0024016 A1 entitled “Parallel Torsion Suspension Assembly”published on Feb. 1, 2007, each of which are hereby incorporated byreference in their entireties), which is shown in more detail in FIG.1D.

The elongate torsion assembly 80 may extend along the pivot axis 14 andbe configured to provide down pressure, or downward force, to the rollerapparatus 40. The elongate torsion assembly 80 may also act as asuspension, by limiting travel and damping movement and vibrations, whenthe roller apparatus 40 of the implement 10 is rolled across a groundsurface 12. The elongated torsion assembly 80 may include a firstelongate member 82 fixedly coupled to the mount portion 20, and a secondelongate member 88 fixedly coupled to the extension member 30. The firstelongate member 82 may include an upper portion 84 and a lower portion86 configured to be coupled together to “sandwich” the second elongatemember 88 therebetween. The elongate torsion assembly 80 may furtherinclude a plurality of cushioning rods 90 located between the first andsecond elongate members 82, 88. The cushioning rods 90 may be configuredto allow movement of the first elongate member 82 relative to the secondelongate member 88 about the pivot axis 14 in either direction asindicated by arrow 92. As such, the elongated torsion assembly 80 may beconfigured to allow movement of the mount portion 20 relative toextension member 30, and vice versa, about the pivot axis 14 in eitherdirection as indicated by arrow 92.

In other words, the elongated torsion assembly 80 may include twoelongate members, a first elongate member 82 and a second elongatemember 88, which may be of similar length, but may differ in crosssection size or shape such that the first and second elongate members82, 88 may be generally concentrically arranged about the pivot axis 14with shock absorbing and/or travel limiting cushioning rods 90 (a rod ofany suitable shape may be used) located therebetween. In someembodiments, the first elongate member 82 may reside or may be locatedwithin the second elongate member 88 as opposed to the second elongatemember 88 residing or located within the first elongate member 82.

In at least one embodiment, the cushioning rods 90 may extend the fulllength of the first elongate member 82 and the second elongate member88. In other embodiments the cushioning rods 90 may be formed insegments and or pieces and may be located at the end regions of elongatemembers 82 and 88. In some embodiments, the cushioning rods 90 mayextend greater than or equal to 40% of the length of the first andsecond elongate members 82, 88, greater than or equal to 50% of thelength of the first and second elongate members 82, 88, greater than orequal to 75% of the length of the first and second elongate members 82,88, or greater than or equal to 90% of the length of the first andsecond elongate members 82, 88. Additionally, the cushioning rods 90 mayextend less than or equal to 100% of the length of the first and secondelongate members 82, 88, less than or equal to 90% of the length of thefirst and second elongate members 82, 88, less than or equal to 75% ofthe length of the first and second elongate members 82, 88, or less thanor equal to 50% of the length of the first and second elongate members82, 88.

In other embodiments, such as depicted in FIGS. 5A-5C, the mount portionmay be pivotally coupled to the proximal end portion of the extensionmember through the use of, for example, a spring, a strut, a shockabsorber, a linear spring/damper system, a rotary or linear hydraulicactuator/accumulator system or any suitable suspension element or systemor combination of such elements or systems, etc.

The extension member 30 may be made, or formed of, metal such as steel,aluminum, cast iron, plastic (e.g., for example, fiber-reinforced orglass-filled) or any other suitable material. Further, the extensionmember 30 may be formed by cutting (e.g., laser cutting, stamping,blanking, water-jet cutting, or plasma cutting, etc.) a sheet ofmaterial and then bending, or forming, the sheet of material into theshape depicted in FIGS. 1A-1C. Additionally, the extension member 30 maybe formed using any suitable method including casting, forging orinjection molding. As shown, one or more cutouts 36 may be defined, orformed, in the extension member 30 to, e.g., reduce weight, provideaccess points for serviceability, provide debris cleanout and/orflow-through for debris, etc.

Further, as shown in FIG. 1A, the extension member 30 may include one ormore stiffening members 38 to, e.g., reinforce the strength of theextension member 30. The stiffening members 38 may be formed by coupling(e.g., by welding, riveting or otherwise fastening process)reinforcement material to the extension member 30, or by the creation ofstiffening features within the extension member 30. The stiffeningmembers 38 may restrict bending, twisting or other undesirabledeformation of the extension member 30 from occurring. The distal endportion 34 of the extension member may extend towards the ground surface12 (e.g., the distal end portion 34 may be angled towards a groundsurface 12, etc., as shown in FIG. 1C) and may be coupled to the rollerapparatus 40 to locate the roller apparatus 40 proximate the groundsurface 12 such that the roller apparatus 40 may engage and contact theground 12 (e.g., for example, continuously, to ensure that the rollerapparatus 40 outer surface 43 of the cylindrical portion 41 maintainscontact with the ground surface 12 and does not bounce off the groundsurface 12, or intermittently, so that the roller apparatus 40 or theouter surface 43 of the cylindrical portion 41 maintains contact withthe ground surface 12 at least a portion of the time) when in use.

The roller apparatus 40 may be configured to engage and lift groundmaterial to disperse the ground material and form a plurality ofreservoirs in the ground surface 12 as the implement 10 traverses theground surface 12. As the roller apparatus 40 traverses the groundsurface 12, the roller apparatus 40 may roll over the ground surface 12.To facilitate the rotational motion of the roller apparatus 40, theroller apparatus 40 may be rotatably coupled to the distal end portion34 of the extension member 30 about a roller axis 16. As used herein,“rotatably coupled” may be defined as a coupling between objects suchthat the objects are rotatable in relation to each other.

The roller apparatus 40 may include a cylindrical portion 41 defining anouter surface 43 and a plurality of ground displacing elements 60 (e.g.,soil displacing elements). The cylindrical portion 41 may extend from afirst end portion 42 to a second end portion 44 defining a roller width47. The roller width 47 (e.g., for example, a roller width sized to bepositioned between crop rows) may be about 8 inches to about 42 inches,such as, e.g., about 8 inches, about 12 inches, about 21 inches, about22 inches, about 24 inches, about 42 inches, or any size in betweenthose described herein, but not limited thereto, etc., and may bedependent on the distance between crop rows for which the implement isintended to be used. Each of the first end portion 42 and the second endportion 44 may be rotatably coupled to the extension member 30 about theroller axis 16 such that the roller apparatus 40 is rotatably coupled tothe extension member 30.

The plurality of ground displacing elements 60 may be coupled to thecylindrical portion 41 and extend outwardly from the outer surface 43 ofthe cylindrical portion 41. The plurality of ground displacing elements60 may be configured to extend into the ground, or beyond the groundsurface 12, to engage and lift ground material when the outer surface 43of the cylindrical portion 41 is engaged with the ground surface 12 asthe roller apparatus 40 and portions thereof such as the cylindricalportion 41 are rolled over the ground surface 12. After the groundmaterial is lifted by the ground displacing elements 60, the grounddisplacing elements 60 may disperse the ground material. In one or moreembodiments, the ground material may dispersed to the sides of theroller apparatus 40, e.g., direction traverse to the forward movingmotion of the vehicle.

As noted, the outer surface 43 of the cylindrical portion 41 may beconfigured to engage the ground surface 12 when the cylindrical portion41 is rolled over the ground surface 12 as shown in FIG. 1C. As usedherein, “engage a ground surface” may be defined as touching, orcontacting, the ground surface 12 while the object is in use. Forexample, when the outer surface 43 of the cylindrical portion 41 of theroller apparatus 40 engages the ground surface 12, at least a portion ofthe outer surface 43 may touch, or be in contact, with the groundsurface 12 at least a portion of the time when in use. Further, in oneembodiment, the exemplary implement 10 may be configured such that theouter surface 43 of the cylindrical portion 41 engages, or contacts, theground continuously or intermittently when in use (e.g., the suspensionapparatus coupling the mount portion 20 to the extension member 30 maytransmit force to the roller apparatus 40 to provide continuous orintermittent engagement between the outer surface 43 of the cylindricalportion 41 and the ground surface 12).

The cylindrical portion 41 of the roller apparatus 40 may define anenclosure (e.g., a hollow drum). For example, in some embodiments, thecylindrical portion 41 may be enclosed by circular disks 45 proximateeach end portion 42, 44 to form an enclosed cylindrical portion orenclosure. In some embodiments, the enclosure may define a sealableopening 51 enabling a user to fill the enclosure with mass-increasingmaterial, and to contain the mass-increasing material within thecylindrical portion, which may enable more force or pressure to beapplied to the ground surface 12 by the roller apparatus 40. Forexample, such an enclosure may be configured to hold fluid material,solid material, or a combination of the two, and may include, but is notlimited to, materials such as water, sand, calcium chloride, methanol,ethylene glycol, and propylene glycol, etc.

As described herein, the plurality of ground displacing elements 60 mayengage and lift ground material, disperse the ground material, and forma plurality of reservoirs in the ground surface 12. Exemplary rollerapparatuses 40 may include any number of ground displacing elements 60.As shown, the roller apparatus 40 includes four ground displacingelements 60. In one or more embodiments, the roller apparatus 40 mayinclude 2 or more ground displacing elements 60, 3 or more grounddisplacing elements 60, 4 or more ground displacing elements 60, 6 ormore ground displacing elements 60, 8 or more ground displacing elements60, 20 or more ground displacing elements 60, etc. In one or moreembodiments, the roller apparatus 40 may include 24 or less grounddisplacing elements 60, 16 or less ground displacing elements 60, 12 orless ground displacing elements 60, 10 or less ground displacingelements 60, 8 or less ground displacing elements 60, and/or 6 or lessground displacing elements 60, etc.

The plurality of ground displacing elements 60 may be spaced in variousmanners and locations about the cylindrical portion 41. For example, asshown in FIG. 1C, the four ground displacing elements 60 are located andspaced equally, equidistantly, and/or equiangularly about thecylindrical portion 60 and the roller axis 16. The four grounddisplacing elements 60 of the exemplary implement 10 may be described asbeing spaced and located 90° apart from one another.

The ground displacing elements 60 may come in many forms, shapes, and/orsizes so as to be configured to engage ground material and lift theground material to disperse the ground material and form a pluralityreservoirs in the ground surface 12 when the outer surface 43 of thecylindrical portion 41 is engaged with the ground surface 12 when rolledover the ground surface 12. When the ground displacing elements 60engage with ground material, each of the ground displacing elements 60may be described as contacting the ground surface and extending into(e.g., beyond) the ground surface 12 so as to displace, or grab, aportion of ground material from below the ground surface 12. After theground material has been acquired by the ground displacing element 60,the ground displacing element 60 may lift the ground material above theground surface 12 and disperse the material such that a reservoir iscreated, or formed, in the ground surface 12. In one or moreembodiments, the ground material that is lifted from the ground may bedispersed such that all, a majority of, or a portion of the groundmaterial is not dispersed back into the reservoir that was created(e.g., may form mounds between the reservoirs in any direction, such asbetween reservoirs within the path of travel of the roller apparatus, oroutside the path of travel of the roller apparatus).

Each ground displacing element 60 may include a blade portion 62 and oneor more attachment portions 64 coupled to the blade portion 62. The oneor more attachment portions 64 may be coupled to the cylindrical portion41 of the roller apparatus 40 to hold, or position, the blade portion 62with respect to the cylindrical portion 41. The blade portion 62 of aground displacing element 60 may define a ground lifting surface 66 anda rear surface 68 opposite the ground lifting surface 66. An elementthickness 69 may be defined between the rear surface 68 and the groundlifting surface 66. In at least one embodiment, the element thickness 69may be about 3/16 inch to about ½ inch (i.e., about 0.1875 to about 0.5inches).

The element width 70 of the ground displacing element 60 may be definedas the distance extending parallel to the roller axis 16 between a firstedge 72 of the blade portion 62 and a second edge 74 of the bladeportion 62 as shown in FIG. 1B. The element width 70 may be about 8inches to about 42 inches, such as, e.g., about 8 inches, about 12inches, about 21 inches, about 22 inches, about 24 inches, about 42inches, or any width in between those described herein, but not limitedthereto, etc.

The element thickness 69 may be defined in relative terms with respectto the element width 70. For example, the element thickness 69 may besubstantially smaller than the element width 70 of the ground displacingelement 60. In other words, the element width 70 of the grounddisplacing element 60 may be greater than the element thickness 69.

The element length 71 of the ground displacing element 60 may be definedas the distance extending perpendicular to the roller axis 16 from thelocation where the ground displacing element 60 is attached to the outersurface 43 (e.g., a tangential point) of the cylindrical portion 41 to adistal edge 73 of the blade portion 62 as shown in FIG. 1C. As shown,the element width 70 is greater than the element length 71. The elementlength 71 may be about 14 inches to about 16 inches, such as, e.g.,about 14 inches, about 15 inches, about 16 inches, etc.

The size of the ground displacing elements 60 may be defined in relativeterms with respect to the size of cylindrical portion 41. For example,as shown in the exemplary implement 10 depicted in FIGS. 1A-1C, theelement width 70 may be approximately equal to the roller width 47. Inother embodiments, the element width 70 may be greater than or less thanthe roller width 47. For example, the element width 70 may be greaterthan or equal to 50% of the roller width 47, greater than or equal 60%of the roller width 47, greater than or equal to 75% of the roller width47, greater than or equal to 90% of the roller width 47, or greater thanor equal to 100% of the roller width 47. Further, for example, theelement width 70 may be less than or equal to 150% of the roller width47, less than or equal 125% of the roller width 47, less than or equalto 100% of the roller width 47, less than or equal to 90% of the rollerwidth 47, or less than or equal to 75% of the roller width 47.

Further, the size of the ground displacing element 60 may be defined interms of a radius 49 of the cylindrical portion 41 that extends betweenthe roller axis 16 and the outer surface 43 of the cylindrical portion41. For example, in some embodiments, the element length 71 of theground displacing element 60 may be greater than or equal to the radius49 of the cylindrical portion 41. For example, the radius 49 of thecylindrical portion 41 may be in the range of about 6 inches to 9inches, such as, e.g., about 6 inches, about 7 inches, about 8 inches,or about 9 inches, etc. As shown in FIG. 1C, the blade portion 62 of theground displacing element 60 extends into and below the ground surface12, as indicated by a blade penetration depth 76 (e.g., the depth theblade portion extends below the ground surface, such as the distance theblade extends or penetrates below a point, axis or plane of contactbetween the cylindrical portion 41 and the ground surface 12). The bladepenetration depth may be less than the length of the blade portion 62.The blade penetration depth 76 may be, for example, in the range ofabout 6 inches to about 9 inches, or any depth in between thosedescribed herein.

The ground lifting surface 66 may be configured to engage and liftground material to disperse the ground material and form a plurality ofreservoirs in the ground surface when the outer surface 43 of thecylindrical portion 41 is engaged with the ground surface 12 as thecylindrical portion 41 is rolled over the ground surface 12. The groundlifting surface 66 is the portion of the ground displacing element 60that may be described as being configured to dig, remove, separate,break apart, and/or lift the ground material out of the ground, andsubsequently disperse the ground material.

The blade portion 62, and/or the ground lifting surface 66 of the bladeportion 62, may come in many shapes and sizes. For example, the bladeportion 62 and/or the ground lifting surface 66 may be substantiallyplanar as shown in the exemplary implement 10 depicted in FIGS. 1A-1C.In other words, the blade portion 62 and the ground lifting surface 66lie, or extend, along a single plane. In other embodiments, the bladeportion 62 and/or the ground lifting surface 66 may be non-planar suchas, e.g. curved, cambered, convex, concave, angled, etc. Additionally,the blade portion 62 may include more than one portion that arepositioned with respect to one another to provide a ground liftingsurface 66 lying in more than one plane, each portion angled withrespect to one another.

The blade portion 62, and in turn, the ground lifting surface 66, ofeach of the ground displacing elements 60 may be configured to extendtangentially with respect to the cylindrical portion 41. In other words,the blade portion 62 may be coupled to the cylindrical portion 41 in atangential orientation, or a substantially tangential orientation. Forexample, each blade portion 62 may extend from the cylindrical portion41 along a plane that is tangential to the outer surface 43 of thecylindrical portion 41. In other embodiments, such as those describedherein with respect to FIGS. 4A-4B, the blade portions and/or groundlifting surfaces may also extend radially, or at any suitable angle,from the cylindrical portion.

The attachment portions 64 of the ground displacing elements 60 mayprovide coupling of the blade portions 62 to the cylindrical portion 41of the roller apparatus 40. In at least one embodiment, the attachmentportions 64 may be fixedly coupled (e.g., for example, welded) to thecylindrical portion 41 such that, e.g., the blade portions 62 of theground displacing elements 60 may be removed and replaced (e.g., theblade portions 62 may be attached to the attachment portions 64 byfasteners 165, e.g., such as, screws, bolts, nuts, etc.). In at leastone other embodiment, the attachment portions 64 may be removablycoupled to the cylindrical portion 41 such that, e.g., the grounddisplacing elements 60 including both the blade portions 62 and theattachment portions 64 may be removable from the cylindrical portion 41and/or replaced by another ground displacing element.

As shown in FIGS. 1A-1C, each ground displacing element 60 may includefour attachment portions 64. In other embodiments, each of the grounddisplacing elements 60 may include less than 4 attachment portions 64(e.g., such as 1 attachment portion, 2 attachment portions, and 3attachment portions) or more than 4 attachment portions (e.g., such as 5attachment portions, 6 attachment portions, 8 attachment portions,etc.). In at least one embodiment, the ground displacing elements 60 maynot include an attachment portion 64 and the blade portion 62 may bedirectly coupled to the cylindrical portion 41. Each of the attachmentportions 64 of the ground displacing elements 60 of the exemplaryimplement 10 depicted in FIGS. 1A-1C are coupled or attached to the sideof the blade portion 62 that defines the ground lifting surface 66(e.g., located on the counterclockwise side of the blade portion asviewed in FIG. 1C).

In other embodiments, such as those shown in FIGS. 3-4, the one moreattachment portions may be attached, or coupled, to the side of theblade portion defining the rear surface, which may be described as thenon-working surface of the blade (e.g., located on the clockwise side ofthe blade portion as viewed in FIG. 4B).

Although the ground displacing elements 60, or members, are describedherein as extending from the cylindrical portion 41 and/or the outersurface 43 of the cylindrical portion 41, the blade portions 62 of theground displacing elements 60 may or may not extend completely to theouter surface 43 of the cylindrical portion 41. For example, a gap 75may be present between the blade portion 62 and the outer surface 43 ofthe cylindrical portion 41. In other words, while the attachmentportions 64 of the ground displacing elements 60 may be in contact with,or coupled to, the cylindrical portion 41, the blade portions 62 may notbe in contact, or touch, the outer surface 43 of the cylindrical portion41.

Another exemplary implement 110 is depicted in FIGS. 2A-2C. Severalfeatures and/or portions of the exemplary implement 110 may be similarto the exemplary implement 10 described herein with reference to FIGS.1A-1D. For example, the mount portion 120, extension member 130,cylindrical portion 141 of the roller apparatus 140, and attachmentportions 164 of the ground displacing elements 160 of the exemplaryimplement 110 may be similar to the mount portion 20, extension member30, cylindrical portion 41 of the roller apparatus 40, and attachmentportions 64 of the ground displacing elements 60 of the exemplaryimplement 10 of FIGS. 1A-1D. As such, such features and/or portions arenot further described herein, and it is to be understood that one ormore such features and/or portions may be used interchangeably betweeneach and every embodiment described herein.

The exemplary implement 110 may include a plurality of ground displacingelements 160 that are configured differently than the ground displacingelements 60 of the exemplary implement 10 described herein withreference to FIGS. 1A-1D. More specifically, the blade portions 162 ofthe ground displacing elements 160 of the exemplary implement 110 areshaped differentially than the blade portions 62 of the grounddisplacing elements 60 of the exemplary implement 10.

Each of the ground displacing elements 160 may include a blade portion162 and one or more attachment portions 164. As shown, each grounddisplacing element 160 includes two attachment portions 164 configuredto attach the blade portion 162 to the cylindrical portion 141. As shownin FIGS. 2A-2C, the blade portion 162 and, in turn, the ground liftingsurface 166, of the ground displacing elements 160 are bent, or angled,so as to define a first portion 190 and a second portion 192. The groundlifting surface 166 of each of the first portion 190 and the secondportion 192 may lie, or extend within, different planes than each otheras shown in the cross sectional view of the blade portion 162 in FIG.2C.

The first portion 190 and the second portion 192 may be angled withrespect to each other so as to be described as being non-planar, or notlying substantially in a single plane. For example, the first portion190 may lie in a first plane 191 and the second portion 192 may lie in asecond plane 193, and the first plane 191 may be different, or intersectwith, the second plane 193 defining an angle 195. The angle 195 betweenthe first portion 190 and the second portion 192 may be between about185 degrees to about 265 degrees. For example, the angle 195 may begreater than or equal to about 185 degrees, greater than or equal toabout 200 degrees, greater than or equal to about 210 degrees, greaterthan or equal to about 220 degrees, greater than or equal to about 230degrees, or greater than or equal to about 240 degrees or more. Further,for example, the angle 195 may be less than or equal to about 265degrees, less than or equal to about 255 degrees, less than or equal toabout 245 degrees, less than or equal to about 225 degrees, or less thanor equal to about 200 degrees, or any angle in between those listedabove, but not limited thereto.

The first plane 191 and the second plane 193 may be described asintersecting at an apex 197. A tip portion of the apex 197 (FIGS. 2A and2C) that is most distal from the cylindrical portion 141 may be thefirst portion of the blade 162 to contact the ground surface 12 when theimplement 110 is being used to form reservoirs. In other words, theblade portion 162 may be pointed like a shovel (see, e.g., chisel tip297 in FIG. 4A).

As shown in FIG. 2C, after the ground lifting surface 166 has liftedground material from the ground, the ground lifting surface 166 maydisperse ground material outside of the roller width, generally ineither direction parallel to the roller axis 16 as shown by arrows 199.In other words, the non-planar or angled, ground lifting surface 166 ofthe implement 110 of FIGS. 2A-2C may be configured to disperse groundmaterial in lateral directions, or directions orthogonal to thedirection the vehicle is traveling. Dispersion of ground material, orsoil, in these lateral directions may move ground material (e.g., createmounds of ground material) outside the width of the roller apparatus140, and outside the roller apparatuses 140 path of travel.

Another exemplary implement 111 is depicted in FIG. 3, which may besimilar to the implement 110 described herein with respect to FIGS.2A-2C. The exemplary implement 111 may be different from the implement110. For example, the exemplary implement 111 may define apertures, oropenings, 163 in the blade portions 162 of the ground displacingelements 160. The apertures 163 in the blade portions 162 may allow someground material to pass through the blade portions 162. For example, theapertures 163 (e.g., may be positioned adjacent the cylindrical portion141) may be configured to prevent a buildup of ground material in aregion of the blade portion 162 proximal to the cylindrical portion 141.Generally, the ground material may be dispersed as described with regardto the embodiment of FIGS. 2A-2C, however, in this embodiment, someground material may also pass through the apertures 163 in the bladeportions 162. Further, the apertures 163 may also provide additionaltillage or breaking up of the ground material. Additionally, theapertures 163 may further reduce the weight of the blade portion 162.

Further, for example, the exemplary implement 111 of FIG. 3 may includeattachment portions 164 that are attached, or coupled, to the rearsurface 168 of the blade portion 162 (e.g., for example, located on theclockwise side of the blade portion as viewed in FIG. 3). Attachmentportions 164 coupled to the cylindrical portion in this arrangement mayreduce the amount of ground material that may be captured or clogged upin the attachment portions 164 or between the cylindrical portion 141and the ground lifting surface 162.

Another exemplary implement 210 is depicted in FIGS. 4A-4B. Severalfeatures and/or portions of the exemplary implement 210 may be similarto the exemplary implement 10 described herein with reference to FIGS.1A-1D and the exemplary implement 110 described herein with reference toFIGS. 2A-2C. For example, the mount portion 220, extension member 230,cylindrical portion 241 of the roller apparatus 240, and attachmentportions 264 of the ground displacing elements 260 of the exemplaryimplement 210 may be similar to the mount portion 20, extension member30, cylindrical portion 41 of the roller apparatus 40, and attachmentportions 64 of the ground displacing elements 60 of the exemplaryimplement 10 of FIGS. 1A-1D. Further, for example, the shape andconfiguration of the blade portions 262 of the ground displacingelements 260 may be similar to the shape and configuration of the bladeportions 162 of the ground displacing elements 160 of the exemplaryimplement 110 of FIGS. 2A-2C. As such, such features and/or portions arenot further described herein, and it is to be understood that one ormore such features and/or portions may be used interchangeably betweeneach and every embodiment described herein.

The ground displacing elements 260 of the roller apparatus 240 of theexemplary implement 210 may be described as extending radially from thecylindrical portion 241 (e.g., from the outer surface 243) as opposed totangentially as in the embodiments described herein with respect toFIGS. 1-3. In other words, the plane in which the ground displacingelement 260 lies or partially lies, may not be tangential to thecylindrical portion 241, and instead, may extend through the roller axis16. Additionally, the element length 270 as shown in FIG. 4B extendingfrom the cylindrical surface 243 to the distal end of the grounddisplacing element 260 may be smaller than the element length 71 of theground displacing members 60 described herein with reference to FIG. 1C.In this embodiment, the element length 270 may be about 6 inches toabout 9 inches such, as, e.g., about 6 inches, about 7 inches, about 8inches, or about 9 inches, etc. Additionally, the element length 270 maybe described in terms relative to the radius 272 of the cylindricalportion 241. For example, the element length 270 in this embodiment maybe less than or equal to the radius 272.

Exemplary implements may utilize various different types of suspensionsystems and apparatus to couple the mount portion to the extensionmember to transmit, transform and/or apply down pressure and/or maintaincontinuous contact between the roller apparatus and the ground surface.For example, the exemplary implement 310 depicted in FIGS. 5A-5C mayinclude a suspension system 380 that utilizes a spring 382 (or othersuitable suspension component) configured to provide suspension and biasabout the pivot axis 14 between the mount portion 320 and the extensionmember 330.

Additionally, the roller apparatus 340 of the exemplary implement 310includes a cylindrical portion 341 and a plurality of ground displacingelements 360 that are different than the ground displacing elementsdescribed herein with reference to FIGS. 1-4. The ground displacingelements 360 of the roller apparatus 340 may be configured to engage andcompress ground material to disperse the ground material to provide aplurality of reservoirs when the roller apparatus 340 engages the groundsurface. In some embodiments, the roller apparatus 340 may not beconfigured to pass in between rows of crops, but may, for example, havea long roller length that is greater than multiple crop rows.

As shown in more detail in FIGS. 5C and 6A-6B, each of the of theplurality of ground displacing elements 360 may define an opening 362extending therethrough configured to receive a fastener 363 such as,e.g., a bolt to couple the ground displacing element to the cylindricalportion 341.

The ground displacing elements 360 may further define a plurality ofground displacing surfaces 366 and a bottom surface 368. The bottomsurface 368 may be configured to be positioned adjacent the outersurface 343 of the cylindrical portion 341. As shown, the bottom surface368 may be curved to match the curve of the cylindrical portion 341.Additionally, the ground displacing elements 360 may define a retentionportion 364 protruding from the bottom surface 368 configured to matewith an opening of the cylindrical portion 341 as described herein withreference to FIGS. 7A-7B.

As shown in FIGS. 7A-7B, the exemplary cylindrical portion 341 maydefine a plurality of secondary openings 392 (e.g., any shaped openings,or combination of openings, including holes, slots, or any othersuitable openings) and a plurality of keyhole-shaped openings 394 (e.g.,shaped openings providing the functionality described herein including alarger opening region adjacent a smaller opening region; such openingregions having an suitable shape). One secondary opening 392 and onekeyhole-shaped opening 394 paired together may be configured to receivethe retention portion 364 and a fastener 363 of a ground displacingelement 360, respectively, to removably couple the ground displacingelement 360 to the cylindrical portion 341. For example, each of theplurality of ground displacing elements 360 may be removably coupled tothe cylindrical portion 341 using a secondary opening 392 and akeyhole-shaped opening 394.

More specifically, as shown in the enlarged region 390 of FIG. 7B, eachfastener 363 may be configured to extend through the opening 362 of theground displacing element 360. During attachment, the fastener 363 maybe first located in a circular region 396 of the keyhole-shaped opening394 such that the head of the bolt may be placed through the circularregion 396 and then the ground displacing element may be slid in thedirection of arrow 399 such that the fastener 363 may be located in aslot region 398 of the keyhole-shaped opening 394. When fastener 363 islocated in the slot region 398, the retention portion 364 may line upwith and be received by the attachment opening 392 to, e.g., assist inretaining the ground displacing element 360 coupled to the cylindricalportion 341.
